Run Portable App from network share on Windows 7/Vista without static network drive
Running a portable app from a network share (UNC, e.g. \\srv\...) and not a static mapped drive providing a drive letter (e.g. Z:\) can disable some funtionality on the app. I will explain how to solve this issue by using the example of FireFox portable.
For me, FireFox and Google Toolbar didn't work as I wanted: The search history was not saved nor was it enabled when running ff from a UNC (under Windows 7, but I guess this is valid for most Windows versions).
